A properly functioning cistern is essential for a smooth-running toilet. But a leaky cistern can be a real pain, wasting water and racking up your bill. Don’t panic! In many cases, cistern leaks are caused by common issues you can diagnose and fix yourself.
This guide will help you understand the reasons behind a leaky cistern and walk you through potential repairs.
Why Your Cistern Might Be Leaking
Several things can cause a cistern to leak. Here are the most frequent offenders:
- Faulty Flush Valve: This valve controls the release of water into the bowl when you flush. A malfunctioning valve can lead to a constant trickle into the bowl.
- Worn-out Flapper Valve: The flapper valve sits at the bottom of the cistern and seals the opening to the bowl. Over time, the flapper can wear out, allowing water to leak from the cistern into the bowl.
- Cracked Cistern: While less common, cracks in the cistern itself can cause leaks.
- Loose Bolts or Connections: The various parts of your cistern are connected with bolts and nuts. If these become loose, they can create leaks around the connections.
Identifying the Source of the Drip
The first step is to pinpoint the location of the leak. Here’s how to play plumbing detective:
- Water Level Check: If the water level in your cistern is constantly running or sits below the refill line, it suggests a problem with the flapper or flush valve.
- Listen Up: A hissing sound near the flush valve might indicate a faulty valve. If you hear water trickling even after the toilet has flushed, the flapper valve might be the culprit.
Repairing Common Leaks
Once you’ve identified the source of the leak, you can attempt a DIY fix. Here’s a breakdown of common issues:
- Replacing a Faulty Flush Valve
A faulty flush valve often shows signs like weak flushes or the handle feeling loose. Replacing it requires turning off the water supply, draining the cistern, removing the old valve, and installing a new one.
- Fixing a Worn-out Flapper Valve
A worn flapper valve might cause the toilet to run continuously. To replace it, simply drain the cistern, unhook the old flapper, and install a new one.
- Cracked Cistern
Unfortunately, fixing a cracked cistern is usually a job for a professional plumber. However, for small cracks (for informational purposes only), you might consider patching with a special epoxy sealant designed for toilets. But remember, this is a temporary solution, and the best course of action is to replace the cistern altogether.
- Tightening Loose Bolts or Connections
Loose bolts or connections can cause leaks around the cistern components. If you suspect this is the issue, turn off the water supply and tighten the bolts with a wrench.
Remember: If you’re unsure about the cause of the leak or feel uncomfortable with any DIY repairs, it’s always best to call a professional plumber.
When to Call in the Pros: It’s Okay to Ask for Help!
There are situations where a plumber’s expertise is the wisest choice:
- Extensive leaks that require replacing parts beyond the flapper or flush valve.
- A cracked cistern that needs professional repair or replacement.
- If you’re unsure about the cause of the leak and don’t want to risk making things worse.
